Description

Betonglegeme for opplagring av den nedre armering vedConcrete body for storage of the lower reinforcement by

fremstilling av stålbetong.manufacture of reinforced concrete.

Oppfinnelsen vedrorer et prismatisk legeme av betong for opplagring av den nedre armering i byggedeler av stålbetong. The invention relates to a prismatic body made of concrete for storing the lower reinforcement in building parts made of reinforced concrete.

Legemer for understøttelse av den nedre armering i betongbyggedeler, såkalte avstandsholdere, er kjent i de forskjelligste ut-forelser. De har til oppgave å opprettholde avstanden mellom bygge-delens underkant og armeringen, f. eks. mellom et tak og armeringen. Avstandsholderne blir vanligvis anordnet rett under stavene eller under krysspunktet til to i innbyrdes rett vinkel anordnede armerings-staver. Bodies for supporting the lower reinforcement in concrete building parts, so-called spacers, are known in a wide variety of designs. Their task is to maintain the distance between the lower edge of the construction part and the reinforcement, e.g. between a roof and the reinforcement. The spacers are usually arranged directly below the bars or below the crossing point of two reinforcing bars arranged at right angles to each other.

For å oppnå en viss homogenitet i materialet har man tilveiebragt avstandsholdere av betong. Disse har form av små, i tverrsnitt trekantede eller kvadratiske klosser som legges under armeringen. Disse klossers tilknytning til armeringen skjer ved at en i klossen innstopt og ut av denne med endene utragende bindetråd bindes sammen med armeringsstavene. Klossens hoyde bestemmer den onskede avstand mellom en betongplates underkant og armeringsstavene. In order to achieve a certain homogeneity in the material, concrete spacers have been provided. These take the form of small, triangular or square blocks that are placed under the reinforcement. These blocks are connected to the reinforcement by tying a binding wire inserted into the block and protruding from it with the ends together with the reinforcing bars. The height of the block determines the desired distance between the lower edge of a concrete slab and the reinforcing bars.

, Oppfinnelsen har til hensikt, under bibeholdelse av de ved disse kjente opplagringer forekommende fordeler å finne en losning som ikke har de hittil forekommende ulemper. , The invention intends, while retaining the advantages occurring with these known storages, to find a solution which does not have the disadvantages encountered until now.

Ifolge oppfinnelsen er det tilveiebragt et prismatisk legeme av armert betong og med innbyrdes parallelle opplagringsflater for opplagring av matter av innbyrdes kryssende og i krysspunktene innbyrdes forbundne staver for den nedre armering i betongbyggedeler, hvilket betonglegeme er kjennetegnet ved at det er stavformet for samtidig opplagring av flere i innbyrdes avstand liggende lengdestaver i en armeringsmatte, og på alle sider begrenses av innbyrdes skråttstilte delflater som stoter sammen i respektive parallelt med de respektive ytterkanter av legemet forlopende kanter. According to the invention, a prismatic body of reinforced concrete is provided with mutually parallel storage surfaces for storing mats of mutually crossing and interconnected rods for the lower reinforcement in concrete building components, which concrete body is characterized by being rod-shaped for simultaneous storage of several spaced apart longitudinal rods in a reinforcing mat, and limited on all sides by mutually inclined partial surfaces which butt together in respective parallel to the respective outer edges of the body extending edges.

Hensiktsmessig dannes betonglegemets tverrsnitt av to likebenede trapeser som ligger mot hverandre med de korte eller lange grunnlinjer. Appropriately, the cross-section of the concrete body is formed by two isosceles trapezoids that lie opposite each other with the short or long baselines.

Betonglegemet ifolge oppfinnelsen har den fordel at en befestigelse til armeringen bortfaller, selv om en slik befestigelse unntaksvis også kan tilveiebringes ved hjelp av de armeringsinnlegg som rager ut av betonglegemet. I normale tilfelle legges legemet helt enkelt på forskalingen, idet de kileformet utover eller også innover utformede sideflater bevirker en god fortanning med betongen, slik at legemet ikke kan falle ut av taket eller kan losne. The concrete body according to the invention has the advantage that an attachment to the reinforcement is omitted, although such an attachment can exceptionally also be provided with the help of the reinforcement inserts that protrude from the concrete body. In normal cases, the body is simply placed on the formwork, as the wedge-shaped outwards or inwards designed side surfaces cause a good engagement with the concrete, so that the body cannot fall out of the roof or become loose.

Andre fordelaktige egenskaper ved oppfinnelsens gjenstand vil gå frem av etterfølgende beskrivelse av de på tegningen viste ut-fore Ise seksempler. Fig.- 1 viser et perspektivriss av et opplagringslegeme med pålagt armeringsmatte. Fig. 2 og 3 viser•tverrsnitt gjennom to utforelsesformer av betonglegemer utfort if51ge oppfinnelsen. Fig. 4- viser et tverrsnitt gjennom et betongtak med armeringsmatte, opplagringslegeme og treforskaling. Other advantageous properties of the object of the invention will become apparent from the following description of the six examples shown in the drawing. Fig. 1 shows a perspective view of a storage body with an applied reinforcement mat. Fig. 2 and 3 show cross-sections through two embodiments of concrete bodies according to the invention. Fig. 4- shows a cross-section through a concrete roof with reinforcement mat, storage body and wooden formwork.

Det i fig. 1 viste flate betonglegeme 1 fremstilles vanligvis fabrikkmessig og leveres i riktig antall til forbrukeren sammen med f. eks. den i fig. 1 viste matte med stavene 2 og 3*Avstanden mellom de to parallelle opplagringsflater bestemmes ut fra den avstand som forlanges mellom forskalingen 5 og armeringen. Legemets 1 lengde holdes alltid slik at gjennomsnittlig to til tre staver 2 (fig. 1) kan ligge opplagret på legemet, hvorhos det skal forefinnes tilstrek-kelig overskuddsflate. Legemets dimensjoner er også slik at disse betongstaver blir usynlige eller nesten usynlige i den omgivende betong. That in fig. The flat concrete body 1 shown in 1 is usually manufactured factory-style and delivered in the right number to the consumer together with e.g. the one in fig. 1 showed mat with bars 2 and 3*The distance between the two parallel storage surfaces is determined from the distance required between the formwork 5 and the reinforcement. The length of the body 1 is always kept so that an average of two to three rods 2 (fig. 1) can be stored on the body, where there must be sufficient surplus surface. The dimensions of the body are also such that these concrete rods become invisible or almost invisible in the surrounding concrete.

Betongstavene 1 fordeles i vilkårlig rekkefolge på flaten som dannes av forskalingen 5» Her er det ikke vesentlig at de legges i en rekke. Det arbeide som trenges for sikring av avstanden til ar-meringsinnlegget består altså i at man valgfritt fordeler opplagrings-stavene over forskalingen. Den tid som kreves for denne frie fordel-ing er praktisk talt uvesentlig..Vanligvis er opplagringsflatens bredde storre enn hoyden til betonglegemet 1, slik at betonglegemet uten videre blir liggende på den flate siden når det kastes på forskalingen. Denne orientering lettes også ved at sidedelene har den spesielle form som f. eks. er vist i fig. 1. The concrete bars 1 are distributed in arbitrary order on the surface formed by the formwork 5" Here it is not essential that they are placed in a row. The work required to secure the distance to the reinforcement inlay therefore consists in optionally distributing the storage rods over the formwork. The time required for this free distribution is practically unimportant. Usually, the width of the storage surface is greater than the height of the concrete body 1, so that the concrete body will easily lie on the flat side when it is thrown onto the formwork. This orientation is also facilitated by the fact that the side parts have the special shape, e.g. is shown in fig. 1.

Det er viktig at betonglegemet har en armering 6 fordi denne armering hindrer at legemene bryter istykker når de kastes på forskalingen. Vanligvis har man en meget grov og uforsiktig behandling under slike byggearbeider. Armeringsstavene 6 kan også være innbyrdes forbundet ved hjelp av tverrstaver. It is important that the concrete body has a reinforcement 6 because this reinforcement prevents the bodies from breaking into pieces when they are thrown onto the formwork. Generally, one has a very rough and careless treatment during such construction works. The reinforcing bars 6 can also be interconnected by means of cross bars.

Ved at legemet har fått den særskilte utforming oppnås at legemet ikke kan falle ut av takdekket etter at forskalingen tas vekk fordi betonglegemet på sett og vis er fastkilt i den oppstopte betong. Because the body has been given the special design, it is achieved that the body cannot fall out of the roof deck after the formwork is removed because the concrete body is, as it were, wedged in the stuffed concrete.

Endedelene' 7 og sidedelene 8 til betonglegemet er hensiktsmessig utfort med kileform. Flatene 8a, b til sidedelene vil således alltid danne en vinkel 10 med opplagringsflåtene 9 som er storre eller mindre enn 90°. The end parts' 7 and the side parts 8 of the concrete body are suitably wedge-shaped. The surfaces 8a, b of the side parts will thus always form an angle 10 with the storage rafts 9 which is greater or less than 90°.

Det er en fordel at betonglegemet har et regelmessig tverrsnitt , f. eks. i form av to méd grunnlinjen mot hverandre lagte, for-trinnsvis kongruente trapeser fordi légemet 1 derved får samme ved-•hefting i betongen uavhergig av pm den viste ovre opplagringsf late blir liggende opp eller ned. Det har også vist seg at legemer som har regelmessig utformet tverrsnitt er bedre å fremstille enn uregel-messig utformede legemer. It is an advantage that the concrete body has a regular cross-section, e.g. in the form of two, preferably congruent, trapezoids placed against each other along the base line, because the body 1 thereby obtains the same adhesion in the concrete regardless of whether the upper storage surface shown is lying up or down. It has also been shown that bodies that have a regularly designed cross-section are better to produce than irregularly designed bodies.

Små og også gjennomløpende riss i betonglegemet, slik de f. eks. oppstår når betongstavene 1 kastes på plass, spiller ingen rolle fordi den innlagte armering 6 holder delene sammen. Small and also continuous cracks in the concrete body, as they e.g. occurs when the concrete rods 1 are thrown into place, does not matter because the embedded reinforcement 6 holds the parts together.

For at betonglegemet 1 skal kunne forankres ytterligere i betongen, er det mulig å la armeringen 6 rage ut av legemet og eventu-elt å forbinde armeringen med takarmeringen. Det er særlig fordelak- tig når legemet 1 også skal være avstandsholder for veggarmeringer. I så fall kan man på en enkel måte boye armeringsstavene 6 til kro-ker 11 som henges på veggarmeringen, slik at avstandsholderne hindres i å gli vekk. In order for the concrete body 1 to be further anchored in the concrete, it is possible to let the reinforcement 6 protrude from the body and possibly connect the reinforcement to the roof reinforcement. It is particularly advantageous when the body 1 is also to be a spacer for wall reinforcements. In that case, the reinforcing rods 6 can be easily bent into hooks 11 which are hung on the wall reinforcement, so that the spacers are prevented from sliding away.
